Abstract
The utility model relates to the technical field of a cable and especially relates to a cable capable of preventing electromagnetic interference. The cable comprises a protection jacket and a plurality of wire cores arranged in the protection jacket. The inner wall of the protection jacket is sequentially provided with a first wrapping band layer and a second wrapping band layer. A shielding layer is arranged between the first wrapping band layer and the second wrapping band layer. Each wire core is formed by stranding at least two wires. The protection jacket is internally provided with at least one shielding layer, so that the cable is capable of preventing the electromagnetic interference generated by wires in the cable when the wires are working at the same time.
Description
Technical field
The utility model relates to cable technical field, relates in particular to a kind of cable of anti-electromagnetic interference.
Background technology
In photoelectricity transmission field, cable is a kind of very important transmission medium, has been widely used in signal transmission technology field at present.Existing cable is transmission of electric signals and power electric simultaneously, but be only by for transmission of electric signals and power electric, this simple structure can not meet cable and be used for transmitting increasing signal element, in addition, because the signal transmission unit in existing composite cable and power supply unit are coated in sheath simply, and signal transmission unit and power supply unit are simple twisting together.The electromagnetic wave producing when like this, signal transmission unit and power supply unit are worked simultaneously can cause the interference on signal.
Utility model content
The purpose of this utility model is to provide a kind of cable of anti-electromagnetic interference, and it has feature rational in infrastructure, effectively to prevent electromagnetic interference.
For achieving the above object, the utility model adopts following technical proposals:
A kind of cable of anti-electromagnetic interference; comprise protection overcoat, be located at the some heart yearns in protection overcoat; on described protection outer casing inner wall, be provided with successively the first belting layer, the second belting layer; between described the first belting layer and the second belting layer, be provided with screen, described heart yearn is formed by the wire bag strand of at least two.
Wherein, described screen is latticed.
Wherein, between described protection overcoat and the first belting layer, can be provided with screen.
Wherein, described the second belting layer inwall is provided with screen.
The utility model beneficial effect: the utility model comprises protection overcoat, is located at the some heart yearns in protection overcoat; on described protection outer casing inner wall, be provided with successively the first belting layer, the second belting layer; between described the first belting layer and the second belting layer, be provided with screen; described heart yearn is formed by the wire bag strand of at least two; the utility model is by being provided with at least screen of one deck in protection in overcoat, thereby prevents the electromagnetic interference that produces when each wire is worked simultaneously in cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
reference numeral
1, protection overcoat; 2, heart yearn;
3, wire; 4, the first belting layer;
5, screen; 6, the second belting layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1; a kind of cable of anti-electromagnetic interference; comprise protection overcoat 1, be located at the some heart yearns 2 in protection overcoat 1; on described protection overcoat 1 inwall, be provided with successively the first belting layer 4, the second belting layer 6; between described the first belting layer 4 and the second belting layer 6, be provided with screen 5; described heart yearn 2 is formed by the wire 3 bag strands of at least two; described screen 5 is latticed; by being provided with at least screen 5 of one deck in protection in overcoat 1, thereby prevent the electromagnetic interference that produces when each wire 3 is worked simultaneously in cable.
In the present embodiment, between described protection overcoat 1 and the first belting layer 4, can be provided with screen 5, described the second belting layer 6 inwalls are provided with screen 5, and described screen 5 can be selected number according to the actual service condition of cable.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
